Do not put the wire wrapped around it will increase the resistance will heat up the fire

Q:In the elevator, on the installation of video lines and telephone lines to go and installation tutorials? (6)

As long as the water is not used with the elbow, with the steel on behalf of the two-way wear should be no problem, the two steel on behalf of the line simmer a small hook, respectively, in the two pass, under normal circumstances should be able to pass through the two bends, In this case the two surrogacy will be in the middle of the bend on the top, and then stir one of the lines, so that hook the other, and then bring out.

Q:High-voltage cable can not be weak and cloth in the same cable trench

In the "construction site temporary electricity safety technical specifications" did not mention water and temporary electricity can not be together, you can press the cable straight to the practice (0.7m above and below the depth of 50mm fine sand backfill original soil, the upper cover Hard protection) to the construction, the appropriate widening of the cable trench, so that water and parallel lines. Wire and cable: wire and cable is the transmission of electrical energy, electrical signals and electromagnetic energy conversion to the wire products. Cables are usually made up of cable cores that transmit electrical or electrical signals and protective, insulated sheaths. A cable with only one cable core and a smaller diameter is often referred to as a wire. Also some wires do not have insulated sheaths, called bare wires. The cable in the cable is made of a metal material with good electrical conductivity, usually copper (good electrical conductivity) or aluminum (lower cost).

Q:Two wires. A red, yellow and blue, a brown, how to dock?

What is the difference, that is, the requirements of anti-ultraviolet wire

Q:The zero line is grounded, why is it still on the pole?

The new house of the wire soaked, the court will support the line, the need for identification. If the identification, the impact of the normal use of the wire, there are security risks, the court will support the line. According to the current market price compensation. But if the identification of the wire does not affect the use, the court will not support the line. The principle of judgment is to repair the repair, not repair only for. Legal link: "Tort Liability Act" Article XVI infringe the property of others, property losses in accordance with the loss occurred when the market price or other means of calculation.

Q:6000 watts of electrical appliances to be large wire bearing

For example: 1000 watts of light to how much wire ah? I want to install a basketball court stadium lights, 4 × 1000 watts, the line is to walk around, each lamp a switch, FireWire with 4 square copper, zero line four common, is 4 square copper, I do not know Is it possible? What is the price of copper? According to my line to the line of the budget about how much? (The stadium around the 30m × 18m this problem is divided into two cases: the principle of power supply: the distance from the long calculation of the pressure drop, the distance from the short diameter of the wire on the capacity to say that 1000W lights with 1.5 square lines on the line But you have to ensure that there is a voltage of not less than 200V on the target, which requires that the resistance of the wire be less than 20V / 5A = 4 ohms. If the long distance from the power supply, please tell the distance and requirements (with aluminum or copper), I give you a calculation. If the four lights, with three-phase electricity better, two of which Each phase of a lamp, the other phase with two lights, each lamp with 1.5 square feet, zero line with 1.5 square enough. We all know that with three-phase power line is it. If it is single-phase power supply, shared zero Line should be 6 square, this is the design requirements, you can use the amount of fine, no matter what.

Q:Cable cable price (how much money a roll)?

4 square copper wire in the 230 --- 300 yuan per 100 meters, 2.5 square copper core line in the 160 --- 200 yuan per 100 meters, look at the region to see the market at that time.
